ble connection issue

[kk]

HI,all!

Recently my nrf51822 device encountered a tough issue,the detials are:

My device connected to an android app, which has some bugs about ble connection so the connection is not stable and secure. And because of that, my device's code run out of contorl:

cannot go back to the while circulation in main function, but still can enter rtc and gpiote interrupt. So I think the code might be stuck in some loop function.

So my question is: Will some inlegal behaviours about ble connection cause the code be stuck in someplace? If so, how to advoid this?

I am using sd6.0 and sdk 5_2. Thank you!

Seems like your code is stuck in some APP_ERROR_CHECK condition failure .. when you are in the loop function you mentioned, check the call stack.

thanks for your fast reply, but APP_ERROR_CHECK will cause a system reset instead of stucking in someplace, is that right?

The default behaviour is system reset, but there is flag (i cannot remember it from top of my head, i will check when i go to office)i have seen debug_assert_handlers looping. If you did not enable any debug flags then this is not a reason for you. Can you give me your code for me to try it out? if not please give more information about the loop function

The flag is 'DEBUG', ie if you compile with DEBUG set, as with any debug build, then the behaviour on the default handler is to turn all the LEDs on and loop. In anything where DEBUG is not defined, ie release mode, you get a system reset.

And as I say often - everyone should put a breakpoint in the app_error_handler() routine as a matter of course.

Thanks RK for pitching in :)
